Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 77063 covers

This service adds tomosynthesis images of both breasts to a screening mammogram. An x-ray tube moves across each compressed breast, and the acquired images are reconstructed into thin slices that help the radiologist assess overlapping tissue. A mammography technologist obtains the images in a hospital outpatient department, freestanding imaging center, or mobile mammography unit. The radiologist interprets the tomosynthesis images alongside the screening mammogram’s standard or synthesized two-dimensional images.

Report 77063 once with bilateral screening mammography code 77067 when tomosynthesis of both breasts is performed and interpreted; it cannot be reported alone. The report should document bilateral tomosynthesis and its interpretation. As an add-on, 77063 is paid within the primary procedure’s global period. Its price already accounts for both breasts, so modifier 50 does not increase payment. Modifier 26 identifies the radiologist’s interpretation, modifier TC identifies the equipment and staff portion, and an unmodified claim represents the global service. For Medicare diagnostic tomosynthesis, use G0279 with the applicable diagnostic mammography code instead.
